I was there tonight.  She looked hella radiant, but it didn't take (or 
shouldn'ta taken) my psych BA to quickly deduce (as she owned up to) that 
it was a "new" "guy" in her life, that was making her appear so.  *grin*

Maybe I am getting wise, instead of getting old.

I remember when I first saw the output of the DOS command "dir" on a 
server running MS Exchange.  I was on it to do some tape rotation.

"SOMEBIGHUGESINGLEFILE.EDB" 98123752398572389275 KBytes (or something)

or something like that... it was one huge file!  the whole server was one 
...huge database file?  I couldn't believe it.

So tonight when we were talking about RAID 0 1 4 and 5.00006 :) I still 
find it amazing that for example, MS Exchange can run on 3 HDD's and you 
can just suddenly PULL OUT ONE HDD and everything goes on fine unaffected!

When we talked about load balancing, I meant to ask - with a huge website 
such as yahoo or google, where is the computational power "happening" that 
is constantly monitoring something similar to "top" or "ntop" so as to 
*know* where to reroute balancing to?  (I am dumbing this down undoubtedly.)

Would that fit on the USB thumbdrive that's in my wallet?  ;) Not til 3010.

Yes we talked about a dog.  You did.  *smile*

Anyone reading this who hasn't come to a monthly, you should, it is 
dinner, and social and unstructured and good-natured.  Peace, propz.
